Consider cold windy breeze parallel to your face, with an average facial dimension along the flow of 5cm. The air velocity is 1 m/s (corresponding to 2.2 miles per hour). Assume laminar flow.
Required:
a. Calculate the thickness of the velocity boundary layer at the end of the 5cm length.
b. Calculate the thickness of the thermal boundary layer at the end of the 5 cm length.
c. Provide the physical meanings of the two thicknesses in items 1) and 2).
